“DoBuff” is primarily built around Reminders and Calendar, providing core features such as time management, progress tracking, goal management, and more. “DoBuff” is designed to enhance Reminders and Calendar with a range of powerful additional features, helping you use them more effectively. “DoBuff” started as a collection of tools I built for my own use with Reminders and Calendar. It was developed around my personal needs and is now available for anyone with similar needs. If you are also a Reminders or Calendar user like me, “DoBuff” may be a great fit for you. Core features and goals (supported for both Reminders and Calendar events): 1. Display tasks and events on a timeline. 2. Unique weekly, monthly, and yearly planning views. 3. Two separate tag systems that can be used independently or synced with Reminders. 4. Focus timers based on Reminders for better time management. 5. Progress bars based on Reminders, with lists serving as progress trackers for goals. 6. Completion and time-spent statistics for Reminders lists. 7. Trend analytics, including tag-based focus time statistics, list tracking, yearly heatmaps, time paths, footprint maps, and more. 8. Countdown support for Reminders. 9. Mark Reminders as abandoned or postponed. 10. Calendar integration, including reading events and writing focus sessions to Calendar. 11. Counting and count tracking. 12. Enhancements available for Reminders are also supported for Calendar events. 13. Export and back up Reminders. 14. Reminder countdowns with support for system alarm countdowns. 15. Note templates for quickly adding notes. 16. Add notes to lists. 17. A range of widgets, including Focus widgets, Calendar widgets, Goal Tracking widgets, Today widgets, and more. 18. Automatic focus timing. 19. Favorites for Reminders and Calendar events. 20. Enhanced global search. 21. Apple Watch version. 22. Turn Reminders into anniversary reminders. 23.
